Hooks directly to your booster. Type: Vacuum Pump. Ideal for cars when the proper amount of vacuum is not being generated. Uses a highly effiecient electric pump, relay switch and sitributor with vacuum switch which should be mounted close together for effectiveness.
it would help if they told you about the check valve hidden the tubing. nothing about it in the hand book for install. other than that it is Great. for vehicles with BIG CAMS>
